lord of the flies
Ralph represents leadership, the properly socialized and civilized young man. He is attractive, charming, and very intelligent. He demonstrates obvious common sense. Ralph is the one who decides about the meeting place, the fire, and the huts. He synthesizes and looks after piggy while everyone else bullies him. He recognizes the false fears and superstitions as barriers to their survival. He is a natural leader.
Piggy is the intellectual with poor eyesight, a weight problem, and asthma. He is the most physically vulnerable of all the boys, despite his greater intelligence. Piggy represents the rational world. By frequently quoting his aunt, he also provides the only female voice.Piggy's intellect benefits the group only through Ralph he acts as Ralph's advisor. Piggy gets bullied by the rest of the boys on the island, this is why he is called piggy because he gets called fat all the time.
Piggy also blames everything on his asthma and is always saying huis aunt would not let him do things.
goulding uses piggy's glasses as a symbol for man reasons. 1)the other boys bully him for wearing them.
2) helps him see much more than the others boys for example danger and that the others boys are savages.
3)the glasses help light a fire.
Jack represents evil and violence, the dark side of human nature. A former choirmaster and "head boy" at his school, he arrived on the island having experienced some success in exerting control over others by dominating the choir with his militaristic attitude. He is eager to make rules and punish those who break them, although he consistently breaks them himself when he needs to further his own interests. His main interest is hunting, an endeavor that begins with the desire for meat and builds to the overwhelming urge to master and kill other living creatures. Hunting develops the savagery that already ran close to his surface, making him "ape-like" as he prowls through the jungle. His domain is the emotions, which rule and fuel his animal nature.
The conflict on the island begins with Jack attempting to dominate the group rather than working with Ralph to benefit it. He frequently impugns the power of the conch, declaring that the conch rule does not matter on certain parts of the island. Yet he uses the conch to his advantage when possible, such as when he calls his own assembly to impeach Ralph. For him, the conch represents the rules and boundaries that have kept him from acting on the impulses to dominate others.
sam and eric-
Samneric (Sam and Eric) represent totally civilized and socialized persons. As identical twins, they have always been a group, albeit the smallest of groups, but a group nevertheless. They know no other way than to submit to the collective identity and will. They are initially devoted to rescue but easily overwhelmed by the ferocity of tribe. They represent the well-intentioned members of general public who play by the rules of whoever is in charge. They are easily intimidated by Jack and abandon their fire-tending duties at his command. Seeing Ralph's rage at the resultant loss of a rescue opportunity, Samneric mock him once they are alone, despite the fact that their desertion of duty caused his anger and the loss of possible rescue. On a realistic, perhaps human, level, they may laugh to dispel their guilt or because their childish perspective has already allowed them to forget the loss they caused or because their priority is merely to avoid punishment. On the symbolic level, however, laughter is a totally social act.
Simon's role as an artistic, religious visionary is established not only by his hidden place of meditation but also by the description of his eyes: "so bright they had deceived Ralph into thinking him delightfully gay and wicked." While Piggy has the glasses — one symbol of vision and truth — Simon has bright eyes, a symbol of another kind of vision and truth.
Simon is different from the other boys not only due to his physical frailty, manifested in his fainting spells, but also in his consistently expressed concern for the more vulnerable boys. Littluns follow him, and he picks choice fruit for them from spots they can't reach, a saintly or Christ-like image. He stands up for Piggy and helps him get his glasses back when Jack knocks them off his head, another allusion to Simon's visionary bent. In addition, he has a secret place in the jungle, where he spends time alone.
roger represents the sadist, the individual who enjoys hurting others. His evil motives are different from Jack's, who pursues leadership and stature and enjoys the thrill of the hunt. Roger just likes to hurt people. He is described in Chapter 1 as a boy "who kept to himself with avoidance and secrecy." His secret is that he is, in some ways, more evil than even Jack. All his life, Roger has been conditioned to leash or mask his impulses. The "irresponsible authority" of Jack's reign offers him the chance to unleash his innate cruelty. Initially, in a mean-spirited prank, Roger throws rocks at the unsuspecting littlun, Henry, but he throws them so that they miss, surrounded as Henry is by "the protection of parents and school and policeman and the law. Roger's arm was conditioned by . . . civilization." Once he joins Jack's tribe, he has lost that conditioning and eventually kills Piggy with one boulder, which was not intended to miss.
